This is my experience of diagnosis and treatment as a woman with heart problems and may help others.
Had blood pressure problems for twenty years on 3 tablets for control.
Had chest discomfort - doctor said with tablets shouldn't be problem - stress test - angina - 2 stents.
13 years later - chest pains - hospital - doctor - blood test - probably chest infection - home.
a few days later - chest pains - hospital- doctor - blood test- advised to stay in - 1 stent.
2 years later- chest pain - hospital - Friday - severe chest pain on Sunday - Transferred
Blood pressure 200/100 and something - Consultant - probably reflux or incorrect ECG
2 stents, right side of heart - to return in three months for more stents - covid
After long delay contacted consultant - symptoms returning - don't worry use spray
Finally got appointment - waited all day - wanted to send me home - said I really needed to get sorted as overdue and had travelled miles to hospital in another county - 5 stents
I think if you have a problem, without being rude to hospital staff it is worth persevering and I am still here at 78 to tell the tale and try to make the best of every day.
